jQuery vs. QSA; class/tag/pseudo/attribute selectors (v48)

Revision 48 of this benchmark created by Eamon Nerbonne on

Description

The performance of various jQuery and document.querySelectorAll selectors.

This test page contains some dummy HTML (from html-ipsum.com) just to give the page some weight, make the selectors work a little bit.

Note that the "Tag" selector is selecting a tag that happens to be unique in the page just to be fair.
